Flat-plate and evacuated-tube solar collectors, paired with split or close-coupled tanks. Free hot water from the sun, with electric or gas backup for cloudy days.

Solar hot water is a no-brainer in Australia for households of 3+ — payback of 6–8 years, then 20+ years of near-free hot water. We supply Apricus (evacuated tube), Rheem Loline (close-coupled), Solahart and Stiebel Eltron.
Roof orientation matters — north is best, NE/NW good, E/W still useful, south is poor. We'll assess via Google Earth before specifying.
Flat plate: cheaper, simpler, fine for warm climates and mild conditions. Evacuated tube: more efficient in cold/cloudy conditions, better for southern Australia and high-altitude sites. Both work — we recommend based on location and roof orientation.
North is best (full sun-tracking); NE/NW good (~80% of optimal); E/W still useful (~60%); south is generally not viable. We assess via Google Earth or site visit before specifying. Roof pitch also matters — 22–35° is ideal in most AU latitudes.
Small-scale Technology Certificates (STCs) under the Australian Renewable Energy Target — typical value $1,000–$2,000 off the install cost. State rebates (VEU, NSW ESS) sometimes apply. We handle all paperwork as part of installation.
